' DOMESTIC WATER-SERVICE SYSTM.

Application filed` March 31, 1922. Serial No. 548,449.

To all whom. it may concern Be it known that l, CHESTER ERECORDS, acitiz'en of theUnited States of America, residing at Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Domestic Water-Service Systems, of which the lfollowing is a specification.

rThis invention relates t an improvement in` domestic water service systems, wherein,

a tank or container is adapted to `supply the domestic needs.

llt is usual in such systems to supply the tank from a suitable source thru the use'of pump construction providing means for regulating the quantity of air admitted; and the system roviding proper control means for automatlcally cutttmg in or cutting out the pump in accordance with the pressure, and for preventing tank pressure on the pump when the latter'is idle.

The invention is illustratedlin the accompanying drawings, in which Flg. 1 is a view in elevation, illustrating more or less diagrammatically the improved system.

Fig. 2 is a sectional view partly in elevation, showing the motor and improved pump operated thereby. y

Fig. 3 is a vertical section on the lineA 3 3 of Fig. 2. i

Fig. e isy a sectional detail of the air valve. t

En the drawings, the general -system is shown as a service pipe 1, leading to a pump 2 and a supply pipe 3 leading from the pump to the domestic tank 4, from which the house service pipe 5 leads.

e invention is particularly concerned with the construction of the pump 2, such being shown as operated by an electric movpressure channel 13 of the tor 6, fromone cover plate 7 of which extends removably connected brackets 8 supporting at their outer ends, preferably integrally, an inner wall 9 of the pump housing. The opposite Wall 10 of the housing has anedge flange 11 seating in a shouldered portion 12 of the Wall 9, the annular Huid pump being formed in the flange 11. The impeller 14 operating within the housingfbetween the walls 9 and 10 is secured directly upon the shaft 15 of the motor 6, this impeller comprising a series of particularly -formed blades 16 radiating in curved relay tion from the hub of the impeller to the inner surface of the flange 11. These blades are of hollow formation and divided for a portion of their lengths bya partition 17, forming on one side a water channel 18 and on the opposite side an air channel 19. These channels beyond the end of the partition 17 merge into the' main blade channel 20. The service pipe 1 leads thru the wall 10 of the pump housing into an annular channel 21, with which the water side channels 18 of the impeller blades communicate. The air channels 19 of these blades commu- -nicate withl an annular air pocket 22, be-

tween the hub of the blade and the bearing portion of the rear wall 9 of the housing.

An air valve 23 shown in detail in Fig. 4 communicates with the air pocket 22 thru a port 24 in the wall' 9. rll`his air valve which comprises a removable casing, prei'- erably constructed in sections as shown, has a-lateral port 25 open to the atmosphere and a longitudinal port 2Q controlled by a manually operable valve 27. A construction similar to the well known inner tube tire valve is employed, includin a spring pressed valve 28 is arranged 1n the lower portion of the channel of the air valve, this port valve 28 serving to prevent outflow of Water thru the air valve when the pump is idle, and also serving to hold the air within the pump when the pump is idle, so that the pump ma be said to be primed, that is supplied wit Aair and Water readyfor initial action. f A check valve 29 is arranged in the service pipe 1, to prevent returndiow of the water, and a check valve 30 is arranged in ics the suppl pipe 3 immediately ad'acent the pump, 'this latter check valve to relieve the pump of tank pressure While the pump is idle, and thus prevent undue load on the motor in starting. A pressure switch 3l is arranged above the pump, this switch being operated and controlled by pressure iii thesupply pipe 3, the Water under pressure bein delivered from said supply pipe beyon' the check valve 30 to the pressure switch by a pipe-321 'lihe pressure switch which may be of any desired type is designed to be controlled by the pressure of the fluid in the pipe 3, the switch being set so that at' a predetermined pressure the Operating circuit to themotor 6 is open, any pressure less than the predetermined pressure serving to close this circuit and start the pump thru the motor.

vF rom the above construction, it Will be apparent that in the operation of thel pump, Water and air are admitted in separate channels and finally mingle in the impeller blades v .and then forced from the channel 13 thru the supply pipe 3 to the tank Ll. The air contained in the Huid stream will of course accumulate above the Water in the tank and operates as a pressure'medium to cause the Water to How thru the house service pipe 5 While the pump is idle. f The particularly important feature of the present invention is the provision ofi/ a pump built conjointly with the motor and peculiarly adapted to simultaneously deliver air and Water to the household tank,

the admission-of either water or air being independently controlled, in order that their co-mingling in a inal stream will introduce with the Water in the tank a sufcient quantity of air to maintain a pressure upon the body of water in the tank. It is to be particularly noted that the pump and niotor Aare substantially a unit, in that the base of the motor serves'as a base and support for the pump, and the motor shaft is continued to provide the l pump shaft.

What I claim is:

1. A pump for pressure systems, including a casing, an impeller therein having independent blades, each of said blades being interiorly formed to provide a water channel and an air channel, these channels delivering into a main channel at the end off'the blade,v the impeller having-a hubspaced from the casing at one end to provide an air pocket with which the air channels communicate, means open only to inward tlovv' for admitting1 air to said air pocket, the opposite end of ther hub having an annular space in. communication with a water supply, said annular space being iniopen com-\ munication vvith the Water channels of the blades, the casing having a `itluid-pressure outlet channel in substantially direct open communication With the main channels of the blades, and means for operating the impeller. y

Lacasse 2. A pump for pressure systems, including a motor, brackets secured to and extending from the motor, a pump casing carried by said brackets. the motor having a main shaft extended through one wall of the casing, an impeller mounted Within said casing and havino a-hollow hub secured upon the motor shatt, the shaft maintaining the impeller hub spaced from one Wall of the casing to provide an air pocket, the end oi the hub opposite the air pocket,4 being formed with an annular Water channel, and means for combining and delivering air from the air pocket and Water from the Wai ter channel in the operation of the impeller.

3. pump for pressure systems, including a casing, an impeller therein having independent blades, each of said blades being interiorly formed to provide a Water channel and an air channel, the air channel being of less sectional area than the Water channel, these channels delivering into a main channel at the end of the blade, the impeller having a hub spaced from the casing at one end to provide an air pocket with which the air channels communicate, means open only to inward How for admitting air to said air pocket, the opposite end of the hub-having an annular space in communication with a water supply, said annular space being in open communication With the water channels of the blades, thelcasing having a fluid-pressure outlet channel in substantially direct open communication With the main channels of the blades, and means for operating the impeller.

4. A pump for pressure systems, including acasing, an impeller therein having independent blades, each of said blades being interiorly formed to provide a Water channel and an air channel, these channels delivering into a main channel at the end of the blade, the impeller having a hub spaced from the casing at one end to provide an air pocket Withwhich the air channels communicate,`a spring pressed valve carried by the casing and opening under suction in the lill.
